Cadence-AMS simulator 2.0
Dec 11th, 2003, 12:19am
 
Hello everyone,
I am in the process of setting up the Cadence-AMS 2.0 environment for Verilog-AMS and am facing problems with the cds.lib and hdl.var files.
On debugging the cds.lib file using the  'nchelp -cds.lib' command, I am getting the following error:

ra.ececs.uc.edu ~/verilog11-9> nchelp -cdslib
nchelp: v03.35.(s016): (c) Copyright 1995 - 2002 Cadence Design Systems, Inc.

     I would be grateful if someone could point out the mistake I am making in the whole process.

Thanks and regards,

Guneet,

From the error messages, I would guess that you have an INCLUDE or a SOFTINCLUE
in your cds.lib file which is including an hdl.var file. That's not the correct
thing to do. An hdl.var file (whilst similar syntax) needs to be kept separate
from the cds.lib file.

I managed to get similar error messages by doing the above.

You didn't actually post your cds.lib file, so it's hard to be certain, but
this seems a likely explanation to me.

Also, AMS20 is a rather early version of AMS Designer, and I'd definitely
recommend moving to a newer one (e.g. LDV51) if you can. Things have
moved on a lot in AMS Designer.

Regards,

Andrew.

Mr. Beckett,
    Thanks a lot for the responses both here and on the comp.cad.cadence Google group. I am indeed very grateful to you for that.
Regards,
